Yukawa, known for her tidiness, consistently hangs her coat on the rack at the office, contrasting with her colleagues who casually drape theirs over chairs. This unique habit stems not just from her sense of propriety but also from her fondness for receiving handwritten notes from coworker Mizuki. Initially acquainted with Mizuki solely through a distance and her delightful vanilla fragrance, Yukawa's world changes when a coat mix-up leads to a newfound friendship with Mizuki. Their communication thrives through exchanged notes, inviting Yukawa to post-work outings without the need for prior arrangements or knowledge of each other's contact details. As Yukawa delves into her emotions and uncovers more about Mizuki, the question arises: could their bond transcend its current state and evolve into something deeper?
